About the book: 2017 / God - a fantasy of believers, an illusion of the brain? Mystical experience - the fruit of self-hypnosis, mental pathology? Is the mind a banal biochemical process? Is the search for the meaning of life a primitive adaptation mechanism? Is the soul just a successful poetic image? Is there really no scientific evidence for the immaterial origin of everything that moves us to a sublime understanding of the universe and ourselves in it? This book is an impressive scientifically based response to the most famous studies of human spirituality, religiosity and mysticism, assigning God a unique place to exist - the human brain and describing faith as an adaptive evolutionary mechanism that allows one to adapt to the environment in order to survive.
